Plastic Abrasive

What are the Types of Plastic Abrasive Media?

There are two basic types of plastic media: urea-methanal and resin-bonded polyester. Urea-methanal is the gentler of the two types and is regarded as synthetic media that can produce a bright, reflective finish on materials that will not undergo an additional electroplating step as part of the finishing process.

 Resin-bonded polyester produces a smoother finish and results in very good anodizing, which increases the thickness of the oxide layer on the surface on the substrate. 

Common Plastic Media Blasting Applications (Stripping and Cleaning) And Industries

Plastic abrasive media is now the preferred choice for paint stripping applications in the automotive industry. Most plastic media are harder than paint but softer than the thin gauge sheet metals used to manufacture automotive parts such as hoods, fenders and frames. Thus, the plastic media blasting process will cut, shear and lift the paint without damaging the part surface.

And since plastic media blasting is a dry process, there is no residual flash rust and no concerns about warping or pitting.
